Lebab
Turn your ES5 code into readable ES6
Turn your ES5 code into readable ES6. Lebab does the opposite of what Babel does. Lebab transpiles your ES5 code to ES6/ES7. It does exactly the opposite of what Babel does. Convert your old-fashioned code using the lebab cli tool, enabling a specific transformation. The recommended way of using Lebab is to apply one transform at a time, read what exactly the transform does and what are its limitations, apply it to your code and inspect the diff carefully. Transforms can be applied with relatively high confidence. They use pretty straightforward and strict rules for changing the code. The resulting code should be almost 100% equivalent to the original code. Transforms should be applied with caution. They either use heuristics that can't guarantee that the resulting code is equivalent of the original code, or they have significant bugs which can result in breaking your code. -

Lightning Design System for React
Salesforce Lightning Design System for React
Accessible, localization-friendly, presentational React components. The Lightning Design System for React is an implementation of the Lightning Design System with accessible patterns and established best practices. The source code is licensed under BSD 3-Clause. For a no hassle setup and compatibility with Create React App, transpiled ES6 and CommonJS module versions have been included within the NPM package. If using this setup, please re-write the import statement in the documentation site examples. Advanced usage requires that your babel presets are set up correctly. create-react-app and environments that do not transpile code within node_modules are not compatible with the component import below. All the examples on the documentation site use this syntax. You can use the Babel preset, @salesforce/babel-preset-design-system-react, to get started. This preset will keep Babel compatible with Design System React and allow ES6 module benefits such as tree-shaking. -

Markdown
WeChat Markdown Editor
WeChat Markdown Editor | A highly concise WeChat Markdown editor, that supports Markdown syntax, color palette selection, multi-image upload, one-click document download, custom CSS style, one-click reset, and other features. Markdown documents are automatically rendered into WeChat graphics and text in real-time, so you no longer have to worry about the typesetting of WeChat articles! As long as you know the basic Markdown syntax, you can make a simple and beautiful WeChat graphic. Chrome browser is recommended for best results. In addition, for domestic (China) friends, accessing Gitee Pages will be relatively faster. The existing open-source WeChat Markdown editor has complicated styles and does not meet my personal aesthetic needs. When I use them for article typesetting, I often have to make some changes myself, which is time-consuming and labor-intensive, so I did secondary development. -

Metro
The JavaScript bundler for React Native
Metro aims for sub-second reload cycles, fast startup and quick bundling speeds. Works with thousands of modules in a single application. Supports every React Native project out of the box. Instead of creating the full server, create a Connect middleware that answers to bundle requests. This middleware can then be plugged into your own servers. The port parameter is optional and only used for logging purposes. The onBundleBuilt function is optional, is passed the bundle name, and is called when the server has finished creating the bundle. Starts a full Metro HTTP server. It will listen on the specified host port, and can then be queried to retrieve bundles for various entry points. If the secureServerOptions family of options are present, the server will be exposed over HTTPS. -

Mocha
A feature-rich JavaScript test framework running on Node.js
Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases. Hosted on GitHub. Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. Mocha is the most-depended-upon module on npm and Mocha is an independent open-source project, maintained exclusively by volunteers. Given Mocha’s use of function expressions to define suites and test cases, it’s straightforward to generate your tests dynamically. No special syntax is required — plain ol’ JavaScript can be used to achieve functionality similar to “parameterized” tests, which you may have seen in other frameworks. -

Nock
HTTP server mocking and expectations library for Node.js
HTTP server mocking and expectations library for Node.js. Nock can be used to test modules that perform HTTP requests in isolation. For instance, if a module performs HTTP requests to a CouchDB server or makes HTTP requests to the Amazon API, you can test that module in isolation. Nock works by overriding Node's http.request function. Also, it overrides http.ClientRequest too to cover for modules that use it directly. -

OpenMemory
Local long-term memory engine for AI apps with persistent storage
OpenMemory is a self-hosted memory engine designed to provide long-term, persistent storage for AI and LLM-powered applications. It enables developers to give otherwise stateless models a structured memory layer that can store, retrieve, and manage contextual information over time. OpenMemory is built around a hierarchical memory architecture that organizes data into semantic sectors and connects them through a graph-based structure for efficient retrieval. It supports multiple embedding strategies, including synthetic and semantic embeddings, allowing developers to balance speed and accuracy depending on their use case. OpenMemory integrates with various AI tools and environments, offering SDKs and APIs that simplify adding memory capabilities to applications. OpenMemory also includes features like memory decay, reinforcement, and temporal filtering to ensure relevant information remains prioritized while outdated data gradually loses importance. -

OpenWhip
Optimize interaction with AI coding assistants
OpenWhip is a desktop utility built as a cross-platform Node.js application that humorously gamifies interaction with AI coding assistants by simulating a “whip” tool to interrupt and motivate them during long or stalled operations. The application runs as a lightweight system tray program and overlays a visual whip animation on the screen when activated, creating an interactive and slightly absurd interface for user engagement. Its core functionality is surprisingly practical beneath the joke: when triggered, it sends a keyboard interrupt signal (Ctrl+C) to halt the current AI process, effectively giving developers a quick way to stop unresponsive or slow-running tasks. In addition to the interrupt, the tool also delivers randomized “encouraging” or humorous messages, blending utility with personality and making the experience more entertaining. -

Operator Mono Ligatures
Add ligatures to Operator Mono similar to Fira Code
Add ligatures to Operator Mono similar to Fira Code. This project will generate new OpenType fonts for Operator Mono that includes ligatures similar to those found in the popular Fira Code font. These ligatures were custom-created using Glyphs. There are even italic versions of the ligatures. All new redesigned ligatures with better hinting. Updated font generation to support advanced OpenType features like those found in Fira Code. For example, the cursor now moves inside the ligature. It also handles repeating characters properly. -

Pendulum Editor
A simple markdown editor for static files (Hugo, Nexo, Jekyll
A simple editor for markdown/txt files. Supports saving changes into git repositories hosted anywhere (git add, git commit). Docker images and built binaries are provided. Written by @TitPetric and licensed under the permissive WTFPL. As you write or scroll either the text area or the preview pane, the scroll positions are synchronized based on percentage. In the case of images in the text, accuracy can be quite off, but it's possible to improve this behavior in the future. Most of the development is basically related to the preview of whatever it is you're editing. The editor itself doesn't care about anything other than the contents of the text file you're opening and trying to save.
